Fucked the girlfriend's sister by mistake
Yosuke is Haruka's boyfriend and they are living together. Yosuke and Haruka work different hours so they have very little time together. Yosuke asks Haruka for permission to have sex today because it has been a long time since they have done it. Haruka agrees to let Yosuke indulge when he comes home from work. When he comes home from work, he sees his girlfriend sleeping, wearing very sexy underwear that makes Yosuke unable to control himself. While they are having sex, he sees the face of the girl underneath, it's Kanon-chan, his girlfriend's little sister! It turns out that today she had a fight with her mother so she came here to hide. Luckily she doesn't stay long, by tomorrow morning when Yosuke comes home from work, she has already gone home. And Haruka promises to make it up to him for today's incident. Coming home, he sees a naked woman, wrapped in just a towel, coming out of the bathroom. Thinking it's his girlfriend because Kanon must have left by now, Yosuke doesn't hesitate anymore. He quickly rushes to her, releasing all the discomfort of the past few days. But while in pleasure, the towel slips off, and the girl he is having sex with turns out to be Kanon! Out of fear and confusion, he loses control and releases all his semen inside his girlfriend's little sister...
